onUrlChanged
Introduced: PhantomJS 1.6
This callback is invoked when the URL changes, e.g. as it navigates away from the current URL. The only argument to the callback is the new targetUrl string.
To retrieve the old URL, use the onLoadStarted callback.
Examples
var webPage = require('webpage');
var page = webPage.create();
page.onUrlChanged = function(targetUrl) {
console.log('New URL: ' + targetUrl);
};
